What you see are not new processes but merely two threads every minute.
One for doing the client part and one for the server part. Thus rewouse

a waitpid (pid, NULL, WNOHANG)). Not really resource intensive. Going
down to 5 seconds would be okay but more will lead to problems with
other applications which want to use a card reader.

Note that gpg-agent makes sure that the tick happens on the full second
so that gpg-agent will wakeup at the same time as other background
processes wake up.
I doubt that gpg-agent is in any way a resource hog even on a real
